What Form 1042-S (2012) Is For
Form 1042-S (2012) reports income paid by U.S. withholding agents to foreign persons, such as foreign corporations, partnerships, and nonresident aliens. The form covers source income subject to U.S. tax withholding, including dividends, interest, and other specified types of income. Withholding agents use this IRS form to show gross income, federal tax withheld, and treaty benefits applied under an approved tax treaty.
When You’d Use Form 1042-S (2012)
Withholding agents must file Form 1042-S when they pay U.S.-source income to foreign persons or foreign corporations, even if no federal tax was withheld due to a tax treaty. The filing is required when income paid includes effectively connected income, scholarship or fellowship grants, or federal procurement payments. Both electronic filing and paper filing must follow Internal Revenue Service rules for accurate reporting.

Step-by-Step (High Level)
Step 1: Identify reportable income paid
Determine all income paid during the year that qualifies as U.S.-source income subject to withholding. This may include dependent personal services, independent personal services, dividends paid, or income codes associated with financial institutions and foreign partnerships.
Step 2: Gather required documentation
Collect valid withholding certificates, such as Form W-8BEN or Form W-8ECI, that establish the recipient’s status, foreign tax identification number, and country of residence for tax purposes. These ensure proper application of treaty benefits and accurate reporting.
Step 3: Calculate tax withholding
Apply the correct tax rate under U.S. tax laws. The standard rate is 30% of gross income unless reduced by claiming treaty benefits through a tax treaty. Document each rate used for every foreign person or disregarded entity to maintain tax compliance.
Step 4: Complete Form 1042-S accurately
Enter the following income codes, recipient details, and withholding agent information. Record gross income, tax rate, federal tax withheld, and country details such as foreign postal code. Include any overwithheld tax repaid, and identify the withholding agent’s name for each submission.
Step 5: File Form 1042-S and Form 1042
Submit Form 1042-S to the IRS and provide copies to each foreign recipient by the due date. File Form 1042 to report total income subject to withholding, tax liability, and all federal procurement payments. Use electronic filing when required to ensure timely processing.

Common Mistakes and How to Avoid Them
- Incorrect income codes: Use only the proper codes provided in IRS instructions to describe the income paid. To avoid mistakes, review the list of income codes carefully before submitting your return.
- Missing identification details: Many forms are rejected when the foreign tax identification number or foreign postal code is missing. To prevent rejection, double-check every field before submission.
- Improper use of treaty benefits: Some withholding agents fail to verify the eligibility of taxpayers for treaty benefits. To stay compliant, confirm the taxpayer identification number and signed documentation before applying reduced rates.
- Overwithheld tax not repaid: When an overwithheld tax is refunded, agents must amend the report. To correct errors, submit an amended return showing adjusted amounts withheld.
- Late Filings: Filing after the due date can result in penalties. To avoid penalties, file on time or request an extension before the deadline using IRS Form 8809.
- Incorrect electronic filing format: Errors occur when the format used does not match IRS electronic filing standards. To prevent rejections, follow Publication 1187 for the proper file layout.

What Happens After You File
After Form 1042-S and Form 1042 are filed, the Internal Revenue Service reviews both returns for accuracy and consistency. The IRS verifies that the total gross income, income subject to withholding, and tax paid reported on the federal tax return match the records. Foreign persons may use the form to claim foreign tax credits or refunds through their home country’s tax authorities. Withholding agents must retain copies for at least three years to ensure compliance with U.S. tax laws.
